I'm trying to find out if it possible to have OTA HD cards in the media director and not located in the core? I'm hoping that I can have an OTA HD card(s) in one media director and that it will store the HD .tp stream back to the core. Once stored at the core, I would then be able to playback on any media director ( assuming they have the ability to playback .tp/.ts streams ). Maybe it does this and I'm just to dense to see it but I want to make sure it will work before I go re-wiring 1/2 my house.
